I Application filed January 26, 1920. Serial No. 354,295.

To all whom it may concern:

Be it known that I, JOI-IANN SoHRonnR, citizen of Germany, residing at Bremen, Parkellee 27-29, Germany, have invented certain new and useful Improvements in Devices for Fixing Driving Engines '01.

Electromotors to Machines to be Driven, of which the following'is a specification.

This invention relateslto' a device for fixing a driving engine or an electromotor to a machine to be driven such as machine-tool or the like. The device is destined essentially to be used in connectionwith farm machinery, such as centrifuges, churns, machines for kneading butter, washing machines, mangling machines, pumps and the like. Owing to this invention the coupling of such machines with the driving engine or electromotor can be easily effected Without requiring much transformation of themachine and Without the insertion of a special transmission. It has already beenproposed to drive working machines directly from the motor by means of belt or chain-transmission' The devices of the known types require however a special construction of the working machine for machine-tool in order to permit of the fixing of the motor. On the other hand the devices of known types do not generally allow a secure fixing for the reason that the driving engine or the electromotor is not situated centrally with regard to the machine to be driven so that the working-machines as well as the driving engine or motor suffer greatly from the shaking or from other stress.

This invention consists in providing guiding extensions of the casing of the driving engine, said extensions being situated within the vertical plane of the driving shaft, designed to engage with a hubelike holder when the two machines are being connected; the driving shaft and the driven shaft being accurately in alignment the one with regard to the other. a

The invention further consists in a guidesleeve mounted upon thedriving shaft and designed to be fixed in ahub-like holder when the two parts are being connected.

Other novel features of the invention are; that one of the lateral bearings of the motor casing can serve at the same time as guidesleeve, and that the guiding support is adjustable.

WVith these and other objects in view the invention consists of thespecial combination and arrangement of parts all of whichwill be hereinafter fully described, claimed in the appending claims andshown'in the accompanying drawings, in which;

Fig. 1 is a side elevation of the connecting device; y r Y a Fig. 2' is a front view. of the driving motor and the improved'connecting device;

Fig. 3 shows, on a larger scale, the driving engine, the casing of thesame being partly in sectlon. I

The driving engine or c. The drivingshaft a is to be. coupled in the well known manner with the driven shaft 6 of a machine-tool orfofa working machinefor example of a centr1fuge,by'

electromotor has a shafting foractingupon the drivi'ngshaft ing 6 of the driving engine of motor a, which is situated in the vertical planeof the driving-shaft and serves for ensuring the proper position of the two' shafts c, e in alignment.

The guiding device consists as shown'in Fig.

"3 by way ofexample, of a guide-sleeve g fixed'to the casing *b by means of screw bolts f, the said guide-sleeve 9 being designed to be inserted into a hub-like holder h in which it is fixed through clamping screws 2'. This guide-sleeve gcan form at the same time, the lateral bearing is of the casing Z) for the driving shaft 0 or the said bearing 70 can be extended so as to form the guide-sleeve. In order to ensure an easy and proper adjust ment, the holder h is adjustably connected with the machine to be driven. This adjustable connection is effected, for example,

by .means of asupporting plate Z to which the rod m, which carries the cylindrical gear nor the motor are damaged atthe start. The guide-sleeve 9 can further be bored out in any convenient manner.

It is essential for the invention that the guiding devices be situated close to and Within the vertical plane common to the two shafts so that thus the driving shaft and driving enginemay be fixed and located as centrally as possible with regard to the! shaft to be driven.

I claim:

1. An improved device for fixing to the machine to be driven a driving engine or electromotor'having a shafting, comprising in combination an extension of the casing of the driving engine or electromotor situated Within the vertical plane of the driving shaft and serving as guiding device, a lateral bearing, and a guiding holder fixed to thermachine to be driven adapted to receive the said extension of the casing to secure the shafts of-the driving engine and of the machine to be driven in aligned position.

"2. An improved device'for fixing to the machine to be driven a driving engine or clectromotor having a shaftin'g, comprising in combination, the driving shaft, the casing of the driving engine or electroinotor, an adjustable stand, a guide sleeve projecting from said casing and mounted upon the said driving shaft, a' cylindrical holder adjustably fixed to the machine to be driven for the reception of the said, guide sleeve means for fixing said guide-sleeve in the said holder.

An improved device for fixingto the machine to be driven a driving engine or electromotor having a shafting, comprising in combination, the driving shaft, the casing of the driving engine or electromotor, a guide sleeve projecting from said casing and servingas bearing for the said driving shaft, an

adjustable stand for the holder, a cylindrical holder adjustably fixed to the machine to be driven for the reception of the said guide sleeve and means for fixing said guide sleeve in the said holder. I i

a. An improved device for'fixingto the machine to be driven a driving engine or electromotor having a shafting, comprising in combination, the driving shaft, the casing of the driving engine or electromotor, a guide sleeve projecting from said casing and mounted upon the said driving shaft, a cylindrical holder adjustably fixed to the machine to be driven for the reception of the said guide sleeve means for fixing said guide sleeve in the said holder, and an adjustable stand and means for adjustably fixingthe said holder to the machine to be driven.

5. An improved device forfixing to a machine to be driven a 'drivingengine or electromotor having a shafting, comprising in combination With the driving shaft and With the casing of the driving engine or electromotor a guide sleeveiprojecting from said casing and serving as hearing for the said driving shaft, a cylindrical holder for said guide sleeve, means for fixing the saidsleeve in the said holder, a vertical support for said cylindrical holder, a threaded'lovver part of said vertical support, a support plate
